Can this be patterned?

[RufusToad]

Hi, 

Not sure if this is possible but I was hoping to pattern a notch in a handle grip that has a tapered wall? I think you will see it in the drawing?

Can this be done with patterns or how would you suggest it be done?

Why pattern?

I would do the same as you did.

Hi west,

that seems like a lot of work and thought there would be a simpler way. 
I actually calculated the distances then used a construction line for each gap then drew a box and revolved each one. 
Maybe I did it right but sure thought there would be a simpler way.

Yes, can be done with Pattern, but it is so convoluted I cannot recommend it.

Fusion is so unintuitive; your method would be likely less drama.

Required 3 major workarounds to make it work.

1 Pattern on Path - cannot select a single entity for the Path, has to be the chain of articles.

2 Pattern on Path - cannot flip pattern direction.

3 Path has to be trimmed to avoid the known start position anomaly.

I made a Surface patch of the groove shape (rectangle) oversized because there is no Sketch Pattern on Path.

Pattern these on Path - but I found that Fusion was sending the pattern in the wrong direction

(because I drew the curve left to right and wanted the pattern to go the same way - no way Jose!)

and has no flip option.

This was after I found that Pattern on a Path selects a chain, not individual curves, so had to make a copy path sketch to eliminate the chained Path.

Means I had to move the patch to the other end of the Path.

Revolve the main body.

Revolve the grooves selecting all the patch bodies as the profiles and use Cut.

Ends up the same as one revolve for your method, depends on how tedious your sketch was.

Might help...

Your sketch doesn't make logical sense to me.

One of the slot sides is at an angle and all others are vertical?

Some of the distances are dimensioned as aligned and others as vertical (or horizontal depending on perspective).

The sketch is not fully defined.

If this were my work - I would start over from scratch.

OK, I dug a little deeper and the deeper I dug the less trust I had in the sketch.

What is the source of the original information - where are you getting dimensions?

Why did you use Spline?

@RufusToad

My starting sketch is going to look something like this where I can measure physical dimensions with calipers or mics on lathe.

If I replace this part of the Spline with a 3-point arc it matches within .001 inch at greatest difference (most of curve is essentially the same).

I don't think that you are getting the best advice.

Did you figure out how to do this properly?

[RufusToad]

No, I didn’t, and thanks for the reply!

Posting on Autodesk can be tough—sometimes I get more finger-pointing than actual help. I didn’t constrain anything because I thought there might be a simpler approach, but the arc in the grip really threw me off. I did originally try an ark and not the spline. I reverse engineered this from the originals that came of the handles so I drew a construction line in the middle out the thickness of the grip and then connected that line from top to bottom with an arch then changed to a spline just to try. 

On a positive note, I printed these in TPU, and they came out fantastic! 🙂

Aside from the sketching that needs improvement, I've created a screencast of how I'd do this.

The approach definitely requires less sketching, but it requires knowledge of some surface tools that most newer users don't discover until much later.

[RufusToad]

Thank you soooo much. I would have NEVER went that way with that. I sure thought you could do that in the actual sketch rather than on the body. You made it look simple but you were right that comes with experience and practice. I am going to try and save this video or at least book mark it as this is great learning!!

It was a bit of work for me but in the end I got them printed and they turned out awesome!! That's what keeps me coming back😊

Just hoping TPU will hold up to the heat and weather but with this video I may just design a few different styles for fun.. Thanks again!!

Check back in a while - I am going to create a video using a technique similar to @TrippyLighting but also go into a bit of discussion about logical Design Intent that should be considered by everyone offering to help others.

Still editing a video on intelligent Design Intent to go along with this.

This simple design leads to some very profound discussions involving the domains of beginning and expert designers and also emerging technology like General Artificial Intelligence.
